Former KKK leader running for US Senate

David Duke, a former leader of the white supremacist Ku Klux Klan is running for the US Senate, saying while he believes in equal rights for all Americans he demands respect for "European Americans".

Duke, 66, is a former Louisiana state legislator and unsuccessful Republican candidate for governor who served a 15-month federal prison sentence after pleading guilty in 2002 to charges of tax evasion and mail fraud.

Republican presidential nominee Donald Trump drew criticism in February for failing to quickly disavow support from Duke.

"I believe in equal rights for all and respect for all Americans," Duke said in a video posted on his website.

"However, what makes me different is that I also respect and demand the respect for the rights and heritage of European Americans."

Friday was the deadline for US Senate candidates from Louisiana to register.

Online records posted by the Louisiana secretary of state's office did not show any application from Duke as of midday.
